具有最大Wiener-Hosoya指标的树

Maximum Trees with Respect to Wiener-hosoya Index

为进一步研究分子的性质,M.Randic在文[2]中首先介绍了Wiener-Hosoya指标.Wiener-Hosoya指标能够用h(T)=∑e∈E(T)(h(e)+h[e])组合原理来表示,我们是去计算Wiener指标W而不是去计算Hosoya topologic指标Z.本文主要讨论对于给定的顶点数时具有最大的Wiener-Hosoya指标的树.

Wiener-Hosoya index was firstly introduced by Randi＇c in , which is expected to reveal some further properties of molecular. In this paper, the maximum trees （with respect to Wiener-Hosoya index） with given orders are determined.
